A recent patch moved ACL setting into nfsd_setattr().
Unfortunately it didn't work as nfsd_setattr() aborts early if
iap->ia_valid is 0.
Remove this test, and instead avoid calling notify_change() when
ia_valid is 0.
This means that nfsd_setattr() will now *always* lock the inode.
Previously it didn't if only a ATTR_MODE change was requested on a
symlink (see Commit 15b7a1b86d66 ("[PATCH] knfsd: fix setattr-on-symlink
error return")). I don't think this change really matters.
Fixes: c0cbe70742f4 ("NFSD: add posix ACLs to struct nfsd_attrs")
